Be it known that I, LAWRENCE J r., a, citizen central axis of the sleeve. and inner end of the collar conform to the sh recess 4 when they A. Anno'rr, of the United States, residing the county of Essex and State ofNew Jersey, have invented-certain new and useful Improvements in Bearing-Roll- I ers; and I do hereby declare the following time the coil to bee full, clear,

and exact description of may manner, shrinking the section w 10h the art to which make and use the same. I

This invention relates to bearings and the primaiyxobject of the invention is the pro- I vision of a bearing roller which will efiie sleeve 2 has the bore 6 thereof terciently prevent or absorb end thrust of the I channel 7 which channel is bear-ingand support for rotation within the slibstantially semi-circular in cross section bearing in practically an anti-frictional and receives the substantially semi-spherical manner a shaft or-any suitable device. end 8 of the bearing roller 10. The b rollers 10 are suitable metal in their-ends rounded for forming substantia ly semi-spheres as is clearly shown at 8 and 9 in Fig. 1 of the drawings. The semispherica-l ends 8 and 9 of the rollers 10 are provided for absorbing end thrust of the bearings. The collar 3 has a channel 11 formed in the inner face thereof which re ceives the substantially semi-spherical ends 9 of the bearings 10. he bearing rollers 10 are disposed in a circle within the bore 6 of the casing l for circumferential engagement with the outer surface or circumference of a shaft 12 which is rotatably mounted bearings cating the same and pr ing of the lubricant.

With the foregoing and other objects in ereinafter in the acand claimed.

The cesses 20 are cut inwardly into the inner face sleeve 2 is provided with a facial recess 4 or edge of t-e semi-spherical ends in subforme 1n one end thereof, theside wallsof stantia-lly a half circle and they taper outwhich diverge as they extend inwardly, and wardly and upwardly therefrom in an arcthe inner end Walls of the recess 4 tapers or uate incline of increased radius over the sub inclines outwardly toward the end of the sleeve 2 as it extends inwardly toward the th 2- for forcing the lubricant inwardly toward the center of the rollers during the rotation of the same.

In the rotation of the rollers 10 within the casing 1, lubricant which is and normally or naturally runs' into the ducts 20 when the rollers are stationary, will-upon rotation of the rollers be forced, by centrifugal force; upwardly along the incline of the ducts 20 and into or toward the center-of the rollers or bearings causing-an efiicient lubrication o the bearings. By decreasing the radius of the semi-circular portion of the ducts, a practically abrupt shoulder will be formed which will have a ten ency to prevent the lubricant from flying out of the ends of the bearing during its operation. a

In assembling bearings constructed in accordance with this invention, the rollers 10 and the pin rollers 14 are properly place within the bore 6 of the sleeve 2, after which the sleeve is heated and the collar 3 swage or shrunk therein which properly forms the hearing.

The pin rollers 14 extend longitudinally along the rollers 10 terminating a short distance inwardly from the inner terminal the semi-s herical ends 8 and shown in Fig. 1 of the drawings.

In reducing the invention-to practice certain minor features of construction, combination and arrangement of parts may neces-' sitate alterations to which the entitled provided such alterations prehended within the scope of claimed. I

What is claimedisz- 1. In a bearing structure, bearing rollers being provided with annular lubricant ducts ad acent to their ends, said ducts terminating toward the ends of the rollers in abrupt shoulders and enlarging inwardly toward the center of the rollers in a gradua incline for throwing lubricant inwardly toward the centers of the rollers upon rotation thereof.

2. A bearing are comtapered ends, and heads formed upon an overlying the smaller portions of'said tapered ends.

3. In a bearing structure, the combination with a protective casin of a plurality of bearing rollers rotatab y mounted within said casing, said rollers bein providediwit annular Oll ducts formed t erein a short inwardly from their terminal'ends, said oil du'cts terminating toward the ends of said bearing rollers in substantially semicircular portions and extending inwardly from said substantially semi-circular portions toward the centerof said rollers in an arcuate curve of increased radiuswith refed thereinto v d minals of said semi-sphericalportions, sai

patentee is 7 what islubricant s set to said substantially semi-circular portions for feeding lubricant toward the center of said bearing upon rotation of the same.

4. A hearing roller having tapered ends, semi-spherical heads formed upon the outer smaller ends of said'tapered ends and over- 1 'ng them for forming lubricant receiving ucts, said heads forming abrupt shoulders at the outer terminus of said for throwing lubricant inwardly over the tapered ends toward the centers of therollers u on rotationthereot;

5. abearin structure the combination with a casing, o a lurality of bearing rol ers positioned within said casing, said bearin rollers having their terminal ends rounded and forming substantially semi-spheres, said casing being provide with arcuate channels for receiving said rounded roller (1 ends, said rollers being provided with lubricant ducts formed therein at the inner terlubricant ducts extending into the inner ends of said semi-spherical portions and being substantially semi-circular in shape, said ducts extendin inwardly toward the center of said ro ler from said semi-circular portion in arcuate inclines i of increased radius over the substantially semi-circular portions thereof for feeding lubricant inwardly toward the center of said rollers upon rotation of the same, and a plurality 0 pin rollers spaced within saidcasin and engaging said bearing rollers for he them in spaced relatlon with eachother.

6. In a bearinstructure, the combination with a casing, o a ers positioned within said casing, said hearing rollers having their terminal ends roundsubstantialliy semi-spheres, said casing being provide with arcuate channels for receiving said rounded roller ends, said rollers being provided with lubri-. cant ducts formed therein at the inner terminals ofosaid semi-spherical portions, said ducts extending into the inner ends of said semi-spherical portions and being substantially semi-circular in shape, said ducts extendingiinwardly toward the center of said hearing from said semi-circular portion in arcuate inclines of increased radius over the substantially semi-circular porh tions thereof for feedinglubricant inwardly toward the center of said rollers upon ro tation of the same.
